Subject: Alternative to switch statements

Hi,

I am trying to write a 'keyword-driven test automation framework' in
Ruby.

Using a case statement

<snip>
def field(name, args)
  case name

  when 'username'
    name='login'

  when 'password'
    name='password'
  end

  return $ie.text_field(:name, name).set(args)

end

def button(name)
  case name

  when 'login'
      name = 'Login'

    end

    return $ie.button(:value, name).click

end

<snip>

Calling code

<snip>
field 'username', 'x@x.com'
field 'password', 'password123'
button 'login'
<snip>

I don't like it because

1. It is procedural
2. Lengthy switch statements may affect performance

Could anyone suggest a way using, collections or symbols or something
else?

Thanks

aidy
